Abstract (en)
A method and apparatus for determining and compensating for the crosstalk behaviour and element spacing of an arterial tonometer sensor (100) in order to obtain a more accurate blood pressure measurement. The crosstalk behaviour and the effects of element spacing in a tonometer sensor having a plurality of sensing elements (110) located on a single diaphragm (105) is derived using advanced modeling techniques. An error correction factor look-up table is computed and applied to an uncorrected blood pressure measurement, resulting in increased accuracy.
